Logging Session Results... Well last night I met up with a couple of the lads and did some logging and car diagnostics. The car in question is a 2001 AUM Revo'd S1 A3 with FMIC, Recirc Valve (green spring), K&N Panel Filter, CAT Back Milltek with 94,000 on the clock (original MAF sensor). First conclusion we came to was the Thermostat is nakard as temp readings wouldn;t reach above 73degress even on standstill/idle - I picked up on this issue at teh weekend and then it hit me why I've not been getting ht best of fuel consumption. Anyway that's booked in for replacement under warranty along with fresh coolant and Magnetic Sump Plugs. Lambda Session; Timing Session; A bit more information on parts fitted. Last year teh car had more or less a full service, new plugs, new coils and fresh oil etc etc. CarLube Fully Synthetic Oil 5W40 was fitted at ths time. The engine codes stated on ECP don't match up BUT I have never had any problems at all with them - the original spark plusg on mine had a signle electrode I think; but these I had fitted have 3 (old spark plugs were single electrode and stil have these sat in the loft but not sure how old these are, funny feeling they are originals). Below are the links to the items in question; BERU Audi | Euro Car Parts UKâs No.1 Car Parts Retailer NGK Audi | Euro Car Parts UKâs No.1 Car Parts Retailer Few months ago the car was at Awesome GTi to get a few issues regarding boost and such. I had a FMIC fitted along with the other parts stated above and also had fresh oil fitted. This was about 3,000miles ago (ish) - the plugs and coils remained the same but Ihad new thermostat and temp sensors fitted. The oil Awesome use is 5W30. At the start of May I had the car on the rollers at Awesome; Any help would be greatly apprciated. Cheers. If you need anymore info please ask.
